invention is capable of being incorporated or combined with a truck construction in which is provided an elevating member, such as a platform or a projecting member capable of being positioned below the article or body to be movedvertically, or a .support (such as a skid), or a holder (such as a box), for engaging and lifting the article, body, support or holder, whether such elevating or projecting member is disposed above a portion of the truck frame or projects laterally therefrom, and-whether ornot the raising and lowering mechanism, or a portion thereof, is disposed below the member to be raised and lowered, or such elevating member is supported and guided at its inner end in guidewayscarried bythe truck frame; In the illustrated form of construction I have shown a truck frame having vertical guides, preferably arranged intermediate the ends of the truck frame and slidably supporting the elevating 'member at its inner end so that it may be raised and lowered in carrying out the various operations for which these types of trucks are adapted.

1 indicates as an entirety the truck frame preferably comprising a main or elevated section 2 and a relatively low or sub-section 3. The main or elevated section 2 is preferably constructed as described and claimed in my co-pending application filed Novem- 7 her 20, 1920, Serial No. 425,555, Patent No. 1,554,167. The inner or adjacent ends of'the sections 2 and 3 are preferably connected by a pair of castings 4, each riveted to the ad'- jacent frame members or sections in a well knownmanner.

The relatively low section 3 preferabl comprises pairs of longitudinally exten ing members 5, the elements of each pair being connected together in a well known manner. 6 indicates a pair of wheels disposed below and preferably within the sides of the main or elevated section 2. The wheels 6 are preferably pivoted to an axle (not shown), by means of, knuckle joints, whereby they may be turned for steering purposes. indicates a pair of wheels mounted on an axle (not shown), and co-operating with the wheels 6 to support the frame 1. Where the frame 1 includes a relatively low section 3, as shown in the drawings, the axle for the wheels 7 is connected to the low frame section to position the wheels outwardly of the frame toward the outer end of such section. The wheels 7 are preferably mounted to swing on a'vertical axis or axes for steering purposes, being connected by a suitable steering mechanism, including a hnk 8, to a rod 9 which is connected to the wheels 6 and a steering colunm 10, whereby all four wheels may besimultaneously operated. 12 indicates a motor for driving the wheels 6. The motor 12 is supported in a cradle 12", connected to the axle housing for the power transmitting mechanism (not shown), through which the power of the motor 12 is transmitted to the wheels 6. The axle housing and cradle 12 are preferably supported by a suitable suspension mechanism. .14 indicates as an entirety a source of power supply, such supply in the illustrated form of construction comprising a suitable battery or batteries removably supported on the frame section 2 and arranged to supply current to the motor 12 and preferably enclosed in a suitable casing 14. 14 indicates a controller interposed in and controlling the circuit for the motor 12 in a well known manner. 16 indicates a base or support on which the operative stands when operating the truck and 17 indicates a foot pedal op eratively connected with a brakin mechanism, the braking elements of Wl11Ch serve to stop the rotation of the motor shaft or the propeller shaft connected therewith and operate therethrough to stop or prevent movement of the truck.

18 indicates a pair of spaced vertical guide members preferably arranged intermediate the ends of the truck frame 1. The guide members 18 preferably comprise a pair of I-beams, the inner extending flanges of which serve as guides for shoes 19. The shoes 19 form a part of an elevating member 20, to which re erence will later be made. 21 indicates bars connected at their inner ends to the beams 18 and connected at their outer ends to struts, which may be formed from angle bars 22, disposed at the front end of the elevated frame section 2 and supporting a dash 23 and depending plates 24. The plates 24 carry a pair of brackets 25. The brackets 25 are provided with hollow bosses to receive the opposite ends of a shaft or rod 25 on which the base orplatform 16 is swingably mounted to permit it to be swung upwardly, when not in use, being preferably counter-balanced by a weight 16*. The channel bars 21 are preferably riveted at their inner ends to the I-beams 18, one flange of each of the latter being cut away so that the adjacent bar can be secured directly tothe body portion of the beam.

25' indicates a pair of tie rods, each extending from the joint between the adjacent bar 21 and strut 22 to the upper end of-the adjacent beam 18, being preferably secured to the latter by means of an end plate 26 extending laterally therefrom, as shown in Fig. 1.

The elevating member 20 comprises a shoe member 27 and a horizontally extending member 28- connected thereto. The shoe member 27 preferably comprises a pair of shoes 19, already referred to, connected together by a pair of spaced plates 29 and upper and lower shoe elements 30 carried by each shoe 19 and engaging the inner side wallsof the adjacent beam 18. Each shoe element 30 consists of a roller loosely mounted on a stud shaft 31 supported in the wall of the adjacent shoe 19. The shafts 31 are inclined so that the circumferential surfaces of the rollers may engage the inclined inner surfaces of the side walls orflanges of the adjacent beam 18. As will be understood from Fig. 1, the stud shafts 3l'carried by each shoe 19 are inclined at an angle relative to each other and are offset relative to the central longitudinal plane of the adjacent beam 18, so that the lower roller will engage its rear side wall or flange and the upper roller 'will engage its front side wall or'flange'. The horizontal member 28 preferably comprises a pair of spaced arms 28 extending laterally relative to the shoe member 27 over the sub-section 3 and supporting a plate 28 which may form a su porting means for the materials, goo s,

'struction permitting the platform member to be readily connected at its inner end to the shoe member.

32 indicates as an entirety thehoisting or elevatingmechanism for the elevating member 20. Of this mechanism, 33 indicates amotor, preferably of the electric type, arranged to be supplied with current from the source of supply 14 and operated by means of a controller 33. 34 indicates a supporting member, to which the motor 33 is securedin a well known manner, preferably by cap screws 34*. The lower portion of the supportin member 34 is shaped to form a housing 35 or power transmitting means. 36 indicates a shaft preferably of sectional character, which is driven by the power transmitting means. The sections of the shaft 36 extend laterally in opposite directions through the housing 35 and carry at their outer ends drums 37, 37, to which reference will later be made. pair of spaced standards mountedon the elevated frame section 2, preferably near its rear end and substantially centrally thereof,

and between the guide members 18 and battery housing 14, and serving as a supporting means for the power transmitting means, its supporting member 34 and the 38 indicates a 1 wit motor 33. As shown, these standards are preferably arranged to support the motor 33 with its armature shaft in the central lon itudinal plane of the truck frame 1 and the drums 37, 37', at equal distances from and at the opposite sides of that plane. These standards 38 are preferably provided with front and rear feet, the former being bolted to the rear wall of the frame section 2, or an angle bar carried thereby, and theas an'entirety a brake mechanism for stopping the motor 33 upon the shutting off of current thereto. Of this mechanism, 40 indicates a brake wheel fixed to the extended upper end of the motor shaft 33*. 41 indicates a pair.of brake shoes adapted to engage the brake wheel 40 and stop themotor shaft and through it prevent movement of the elevating member 20 in either direction from the position in which it may have been stopped. The brake shoes 41 are connected to a lever mechanism 42, which operates both shoes simultaneously to apply or release them, such mechanism being operated in the direction to apply the shoes by a sprin '43. 44 indicates a solenold, the winding 0 which is connected in serles with the circuit to the motor 33. The core of the solenoid is connected to the lever mechanism 42 and is held by the latter in its extended or outer position, as shown in Fig. 1. Upon closing of the circuit to the motor 33, the solenoid winding is energized; thereupon the core is moved inwardly, which movement operates the lever mechanism 42, putting the spring 43 under tension and releasing the brake shoes 41. When the oncuit to the motor is opened, the winding is de-energized, which permits the spring 43 to move the core and the lever mechanism 42 in the opposite direction and apply the brake shoes 41 to the wheel 40.

54 indicates a pair of channel bars connecting the upper ends of the guide members 18, being supportedupon and secured to the brackets 26, each fixed to one of the guide members. ,56 indicates hangers disposed between andsecured to the channel bars 54. The hangers 56 are provided with suitable bearings 57 which support the opposite ends of a shaft'58. 59, 59, and 60, 30', indicate pairs of sheaves loosely mounted on the shaft 58 and arranged equal distances from a point midway between the guide members 18. 61, 61', indicate a pair supported at its opposite ends in the channel bars 54 and arranged at right angles to the shaft 58 with its axle in a plane substantially midway between the drums 37, 37 62, 62 and 63, 63, indicate pairs of sheaves loosely mounted on shafts 64, 65, respectively, preferably disposed at opposite sides of and substantially equal distances from the plane in which the shaft 61 is supported and supported at their opposite ends in the plates 29. 66, 66, indicate ropes or other flexible members which run over and around the sheaves and are adapted to be wound on and from the drums 37, 37, to raise and lower the platform 20, together with whatever load is to be carried or transported or moved vertically thereby. The rope 66 extends from the drum 37 over the sheave 59, then around the sheave 62 and then over the sheave 61. From the sheave 61, the rope66 runs aroundthe sheave 63 and then around the sheave 60, its free end being connected to one end of an equalizing element 67, which is pivoted at 68 upon a plate 69 whichforms one element of a take-up mechanism 7 O, the

of sheaves loosely mounted on a shaft 61",

ring in the cables 66, 66, in the event the the sheave 63 and then over the sheave 61.

From the sheave 61 the rope 66 runs around the sheave 62' and then over around the sheave 59', its free end being connected to the opposite end of the equalizing element 67. The operation of winding the ropes on the drums 37, 37, and unwinding them therefrom to raise and lowerthe platform will be readily understood.

71 indicates a switch mechanism, preferably supported on one of the guides 18. The mechanism 71 comprises switches either of which is operated when the shaft 71 is rocked in one direction. The shaft 71 carries an arm 72 to which are pivotally connected the inner ends of rods 73, one extending upwardly and guided for endwise movement by the walls of an opening formed in preferably adjustably fixed to the rods 73 I and adapted to be engaged by a striker or a projecting member carried by the elevated member 20, so that when the latter is moved in either direction, the striker, operating through one of the collars 75, will move the rods 73 and they in turn will open one of the switches of the switch mechanism 71, and thus break the circuit to the motor'33.

No claim is made herein to the switch mechanism 71 as it forms the subject-matter of Letters Patent N 0. 1,726,717, dated Septem- .(see Letters Patent No. 1,690,681, dated Nov. 6, 1928), it is unnecessary to further describe the same herein. I

In the operation of the truck the relatively low section thereof is adapted to be projected or driven under a load to be lifted, transported and discharged. Such load may consist of goods or commodities supported in an elevated position, or a box containing goods, or a skid with the goods thereon. For loadsof a character that can be discharged by tilting the supporting means for the goods and permitting them to be slid off such supporting means, I utilize a dumping mechanism indicated as an entirety at 7 6. The dumping mechanism 7 6 operates when the elevating member is movin vertically, preferably in the downward irection, it co-acting with the raising and lowering means as it movesthe elevating member to tilt the supporting means by holding one end thereof and permitting its opposite end to pivot on the elevating member as it remains supported thereon.

In the form of construction shown in Figs. 1 and 2, the supporting means constitutes a box A into which the oods to be transported and dumped are p aced. The box comprises a bottom a, sides a and a front end wall a ably open, but where it is provided with an end wall, such wall is constructed to form a gate to permit dumping. C indicates an engaging element preferably carried on the outer face of the end wall a The engaging element may comprise a rod extending trans.- versely of the box A and supported at its opposite ends by arms a fixed to the wall a in any desired manner. The rod G extends laterally beyond the sides a of the box A for a purpose which will later appear.

Of the dumping mechanism 76, 77 indicates a shaft supported by the frame 1.

Where the invention is applied to an elevating type of truck having vertical guides, such as shown in Figs. 1 and 2, the shaft 77 is supported by and extends transversely of the guides. In the illustrated form of construction, the brackets 26 support standards 78 that are shaped to provide bearings The rear end is prefers although I do not wish to be limited to this I arrangement. As the shoes 19 are shown in Figs. 1 and 2 as engaging the inner sides of the I-beams, the arm is arranged on the outerside thereof, the object bein to avoid interference between the arm an elements of the raising and lowering mechanism or elevating member. 80 indicates an engaging element, such as a hook carried by the arm 79 (preferably at its free end), ar-

ranged to engage the supporting means as the elevatin member 20 moves vertically. As shown, t e hook 80 extends laterally so that it can hook onto the rod G. 81 indicates a spring preferably connected at one end to the'adjacent tie-rod 25' and atits o posite end to'the arm 79 and normally ten ing to swing it into an inoperative position, that is, in a position inwardly of the guides 1'8 'see dotted lines in Fig. 1and out of the path of movement of the rod C. 82 indicates a means for swinging the arm 79- to move the hook 80 into operative position (seefull lines in Fig. 1). I The means 82 preferably comprise a thrust member pivotally connected at its inner end to arm 79 and extending outwardly to a point within reach of the operative standing on the base 16. The outer end of the thrust member 82 may be guided by the walls of an opening formed in a plate 83 secured to and projecting from the adjacent tie-rod 25' and its free end may be bent laterally, as shown at 82, to form'a handle. By preference, the shaft 77 extends at its opposite ends be yond the guides 18 and carrles two arms 79, each carrying a hook 80, so as to enga ethe supporting means A at its opposite si es to avoid any tendency-of tilting the latter sidewlse.

In the operation of the dumping means 7 6': Fig. 1 shows the truck positioned with its elevating member 20 below a box A. The elevating member is then raised to clear the feet of the box from the floor and the truck driven to the place of discharge. The elevating member 20 is elevated until the' arm C of thesupporting means or box A is above the plane of the hooks 80; then the rod 82 is moved to swing the arms 79 outwardly to the position shown in Fi 1; and then the direction of movement of the raising and lowering mechanism is reversed. As the elevating member descends, the rod C will engage the hooks 80 and be held thereby. As the elevating member 20 continues its downward movement, the box C member 20 is again raised and the hooks 80 released from the arm C, after which the elevating member may be lowered. In Figs. 3 and 4 I'have illustrated my invention in connection with a supportm means such as a skid A. which ma be'o standard size or of any referred orm of construction. Where a stid A is used forthe goods to be transported and discharged, I prefer to provide one or both ends with a projection, such as an angle bar to in- 15 sure a. locking engagement between the hooks and skid A.

In operating the dumpmg mechanism 7 6',

it will be seen that when the hooks engage the supporting means (box A or skid 'A) the latter is held against outward or endwise movement so that it cannot slide off the outer end of the elevating member 20 when it is tilted. This is particularly advantageous since in most instances the rear end of this box or skid extends beyond the elevating member and would readily slide endwise if it were not held by the dumping mechanism 7 6'.

In Figs. 5 and 6 I have illustrated my in- -30 vention in connection with a truck wherein the supporting means comprises a plate 28 pivoted at its outer portion on the elevating member 20, so that it may be tilted relative to the elevating member 20 to discharge the goods thereon by being held at its inner end at or during the time the elevating member moves downwardly. In this form of construction I prefer to pivot the rear end or portion of the plate 28 on the outer ends of the arms 28, these arms being provided with knuckles and the side walls of the plate being provided with hollow bosses to receive the opposite ends of a rod 84, which forms the pintle for such pivotal connection.

When the plate 28" is pivotally connected to the elevating member, the arms 79 are preferably arranged at points between the side edges thereof and in this form of construction the inner end of the plate 28 is formed with cut-aways to receive the arms 79 as the elevating member 20 is operated, 86 indicated rods secured to the under sideof the plate 28" by straps 87 and straddling the cut-aways 85, so that the hooks 80 may engage therewith to tilt or swing the plate 28" as the elevating member moves downwardly, as shown in Fig. 5.

In Fig. 7 I have shown a modification of the construction shown in Figs 5 and 6, wherein the shoes for the elevating member 20 are disposed on the outer sides of the guides 18 and the dumping arms 79 are disposed between the guides. In this form of construction I prefer to operate the arms 7 9 to their in-operative positions by a spring out dip 88 coiled around the supporting shaft and fixed thereto at one end and to the adjacent supporting standard for the shaft at its opposite end.

To those skilled in'the art to, which my invention relates, many modifications and embodiments of the invention and applications thereof will suggest themselves withrting from the spirit and scope thereo The descri tion and the disclosure herein are urely ilustrative and are not intended to in any sense limiting.

The suspension mechanism shown herein forms the subject-matter of an application ointly filed by John H. Hertner and myself-see Letters Patent No. 1,628,145for which reason no claim is made herein to such mechanism.
